Troubleshooting for Each Error Code
E 5 9
Indication
1. Gas cooler outlet temperature sensor connector (2P3) disconnected or contact failure
Probable
2. Gas cooler outlet temperature sensor failure
Cause
3. Control PCB (CS1-PCB) failed
1. Check if the connector (2P3) on the CS1-PCB is disconnected or loose.
2. Check the resistance value of the gas cooler outlet temperature sensor, and check if the
Check
sensor and wiring is open or shorted.
[Method of checking]
Refer to "Method of Checking Sensor Characteristics" in the section "Failure Diagnosis".
1. Correct the attachment of the connector (2P3) on the CS1-PCB.
Corrective
2. Replace the gas cooler outlet temperature sensor.
Action
3. Replace the control PCB (the CS1-PCB).
E 6 0
Indication
1. Inverter-PCB hardware anomaly or failed
Probable
2. Loss of phase (S phase)
Cause
3. Malfunction by noise, etc.
1. Restart power and check if the same problem occurs.
Check
2. Check the power voltage. (Between R-S, S-T, T-R phase)
1. Replace the inverter-PCB.
Corrective
Action
